1,149,586. Grilling oven. SOC. D'EMBOUTISSAGE DE BOURGOGNE. 1 Aug., 1967 [18 May, 1967], No. 35303/67. Heading F4W. [Also in Divisions A4 and H2] An electric grill comprises a lower and upper shell 1, 2, each containing a removably mounted heating resistor of the shielded type with spaced arms 3, 4 set in perforated plates 65, 66, wherein the internal diameter of shell 1 is slightly greater than the external diameter of shell 2 to allow frictionless engagement of the latter within shell 1. Shell 2 comprises two coaxial casing 6, 8 with dome-shaped end walls 10, 12 and parallel cylindrical side-walls 14, 16, terminating in opposite facing annular flanges 18, 20 so. that a channel is formed between them in which is fitted a silicone-rubber 0-ring 22. The said casings are joined together by a threaded rod 24 secured to the summit of the dome-shaped end-wall 10 and fitted with a nut 26 which is rotatably mounted on the dome 12 and secured to a control knob 28. A friction collar 30 allows rotational motion of the control knob with slight sliding friction against the casing 8. The end-wall 10 is so formed to have a chamber 32 with a perforated base 34 and a perforated detachable cover 36 into which is advantageously placed a bottom layer of powdered refractory material and an upper layer of activated charcoal to absorb fat and unpleasant odours from the vapours which then escape through vents 42. The arms 47, 48 of the heater element terminate in socket connectors 49, 50' which are removably mounted by engagement in bores 17 and 44, 46, and comprise a terminal protector 51, covered by an end cap 52, with interposition of a projecting annular ring seal 53, and two connector pins 54 which fit into corresponding plug connectors 57, 58. When plugs 61 are inserted into the corresponding sockets (49, 50), locking springs 55, comprising flexible rods having elbow heads mounted opposite to bores 56, project outward through the said bores thus locking the socket connectors inside the recesses and preventing them from being removed as long as the plug connectors remain in position. In use as an oven a removable grid is provided above element 3 to stand the food on and element 4 is maintained at a predetermined distance from the piece of food to be cooked by locking it in position by turning knob 28. This causes the closure of casings 6, 8 and hence of the flanges 18, 20 thus compressing seal 22 which then projects relatively to the wall 16 with the result that shells 1, 2 are brought into contact with strong friction and coupled together in an airtight manner. A run off cook for meat juices may be added to the annular trough 11, in which the juices are normally collected and prevented from burning by the relatively remote distance from heater element 3. In addition a support 69 at the ends of the elements remote from the arms 47, 48 preventing deflection of said arms and a thermostat or thermal safety system for the electric current supply may also be provided. |
